Once you start wrapping every other libc API that is imperfect, you end
up having your own string library with somewhere around 30 or 40
functions.  And at that point, given that every project has their
slightly different names and slightly different function prototypes,
contributors don't know what to expect from the code.

That's why having a system string library is a good thing.  Everybody
talks the same language.

After all, I don't think it is too much of an issue to write the same
inline function in glibc, once and for all.


Have a lovely day!
